Abstract
- Leiomyoma is a benign smooth muscle tumor that usually arise in the uterus, skin and gastrointestinal system. Only 2 percent are located in the head and neck. Leiomyomas of oral cavity are uncommon as only two cases have been reported in the Korean literature. The common location of oral cavity has been tongue, but other sites include buccal mucosa, lips, palate. mouth floor, and gingiva. Our patient was 30 years old female who complained of swelling and discomfort in the mouth floor. Microscopically this tumor showed bundles of intertwining spindle cells within fibrous connective tissue stroma. The nuclei were generally pale staining and blunt ended. Masson's trichrome stain was positive for muscle, and immunohistochemical study for alpha -smooth muscle actin revealed strong positivity. It was treated by surgical excision. We experienced a case of leiomyoma of oral cavity, so we report with literature reviews
